摘要：

The authors report preliminary measurements on a novel form of SQUID formed from a bulk YBCO ceramic with an adjustable niobium point contact. Weak links are formed at or around the YBCO/niobium interface and the device may be operated either as a DC SQUID or an RF SQUID without readjustment. This has made possible a comparison of the noise spectral density in both modes of operation by a technique which allows the contribution from magnetic flux noise to be determined. The flux noise below 100 Hz is, within experimental error, the same for both DC and RF SQUID modes of operation.
